· JVASP-51583· FeNi2O4

FeNi₂O₄ is a nickel iron oxide ceramic compound belonging to the spinel family of mixed metal oxides. This material is primarily of research and specialty industrial interest, valued for its magnetic properties and thermal stability, making it relevant in applications requiring controlled electromagnetic response or high-temperature ceramic performance. Its dense crystal structure and composite oxide chemistry position it as a candidate for magnetic ceramic coatings, microwave absorbers, and advanced refractories, though it remains less common than simpler iron oxides or nickel ferrites in mainstream engineering applications.
